It sounds like you are on a beta release in the Insider program.

I suggest you restore your phone using the Device Recovery Tool to 8.1 and if you upgrade to Windows 10, stay on the Production or Release Preview branches.

You can use the Backup feature to help keep settings and then restore when back at Windows 10.

Offload photos manually in case they haven't been saved.
